Application filed October 1, 1912, Serial No; 723,305. Renewed February19, 1915. Serial No.9,418.

To all whomit may concern: a

Be it known that I, VVILLIS KENT, of the town of Meaford, in the countyof Grey, in

the'Province of Ontario, Canada, have invented certain new and usefulImprovements n lVood-Sphtt ng Machines, 1 of which'the following is thespecification;

, splitting wedges as hereinafter more particularly explained by thefollowing specification. I

Figure 1, is a perspective view of my device. Fig. 2, is asideelevation. Fig. '3, is a sectional elevation. Fig. a, is an endelevation. Fig, 5, is a sectional detail of the. splitting wedges. a a pIn the drawings like letters of reference indicate correspondingparts ineach figure.

A and A are standardca'stings, suitably supported on a' base B, having aholding trough B V-shaped in cross section into which the wood is fed.The castings A and A are connected together at the top by a longitudinalguide rod B and at the bottomby. longitudinal guide rods 13 and 13*.

C is a hammer provided with sleeve bear..- ings C, C and G slidablymounted upon the guide rods 13 B and 13*.

D, is a cylinder provided with a piston D and piston rod D extendingthrough the end casting A forming one end of the cylinder. The outer endof the piston rod D is threaded or otherwise suitably secured in thehammer C.

l) are suitable operating valves and ducts designed to convey suitablemotive' fluid into the cylinder to reciprocate the'piston Dlongitudinally. r

A is a guide piece secured to a casting A by a suitable bolt A".

A is the wedge'portion of the casting A having vertical guides A inwhich it'is slidably held against the guide piece A".

A is a hardened steel cutting edge secured with the wedge block A bysuitable tap screws A I A is a pulley journaled on a suitable j standardA forming an extension of the casting A j A is a horizontal bearingforming part of the casting A. a f p a A is pull bar provided with aseries of notches A designed to co-act with the projection A formed inthe guideway A A is a cable extending from the pull bar A around thepulley A to the casting A to which it is suitably secured.

A? and A are cutting wedgesformed of hardened steel secured by tapscrews A and A to the casting A so as to form horizontal cutting edges.It will be understood that the casting A is freely held upon the bolt Aso asto'turn thereon.

In operation apiece of cord wood rests in the l-shaped holding groove B,between the hammerC and the cutting wedges A A and A When the hammer Ois driven against the end of the piece of cord wood by means-of thepiston and piston rod D and D respectively theopposite end of the pieceof'cord wood is carried, first against the cutting edge A which splitsthe cord ood vertically. After such vertical split hasbeen startedtheend of the cord wood is brought against the cutting wedgesA and A so asto split the vertically split por- I tions horizontally. By repeatedblowSat the hammer C, the piece of cord wood is split into four quartersfrom end to end. Should the grain of the wood be twisted the horizontalouting wedges A and A will swing around the bolt A so as to follow suchtwist in the grain and thereby prevent any possibility of the cuttingwedges becoming jammed. By pulling the pull bar A longitudinally thehorizontal cutting wedges A and A may be adjusted vertically accord ingto the variations in diameter of the different pieces of cord wood thusinsuring the splitting of each piece centrally at each operation. 7

In order to cushion the blow of the hammer C at each end of the stroke Ihave provided cushion springs H, H H H H and H;

WVhat I claim as my invention is:

1. In a cord wood splitting machine, the combination with a suitablebase having means for holding the cord Wood stick in position, of avertical stationarysplitting wedge and a vertically movable horizontalsplitting wedge located at one end of the I opposite end of the stick,and means for operating the hammer against the stick, as and for thepurpose specified.

2. In a cord wood splitting machine, the combination with asuitable basehaving means for holding the cord wood stick in position, of verticaland horizontal splitting wedges located at one end of the stick, saidhorizontal wedge being capable of vertical movement, and a splittinghammer located at the opposite end of the stickand means for operatingthe hammer against the stick, as and for the purpose specified.

,3. In a cord wood splitting machine, the combination with a suitablebase having means for holding the-cord wood stick in position, of avertical stationary splitting wedge located at one end of the stick, asplitting hammer located at the'opposite end of the stick, meansforoperating the hammer against the stick, and a vertically movablehorizontal cutting wedge located to the rear of the vertical cuttingwedge, as and for the purpose specified. I

a. In a cord wood splitting machine, the combination with a suitablebase having means for holding the cord wood stick in position, of avertical stationary splitting wedge locatedat one end; of the stick andasplitting hammer located at the opposite endof the stick, and means foroperating thehammer against'the stick,rahorizontal cutting wedgelocated'to the rear of, the vertical cutting wedge and piv'otallysupported behind the vertical cuttingwedge so as to tilt in a verticalplane, as and for the purpose specified. Y 5. In a cord wood splittingmachine, the combination with a suitable base, having means for holdingthe cord wood stick in position, of a vertical stationary splittingwedge located at one end of the stick and a splitting hammer located atthe opposite end of the stick, and means for operating the hammeragainst the stick, a horizontal cutting wedge located in the rear of thevertical cutting wedge, and means for adjusting the horizontal cuttingwedge vertically, as and for the purpose specified.

6. In a cord woodsplitting machine, the combination with areciprocatinghammer, ofa'vertical cutting wedge, a base casting for the cutting wedgehaving a vertical guide-way, a horizontal cutting wedge slidablysupported in the guide-way, and means guide-way, a horizontal cuttingwedge slid-' ably supported inthe guide-way, a notched pull bar held ina horizontal bearing adapted to coact with the notches of the pull barto adjust the longitudinal position of the pull bar, a suitably mountedpulley, a cable extending from the pull bar around the pulley to thehorizontal cutting wedge to which it is attached, as and for the purposespecified.
